What Is BASIX?
BASIX (Building Sustainability Index) is a mandatory environmental assessment tool used in NSW. It ensures residential developments achieve minimum energy and water efficiency standards.
The certificate forms part of your DA or CDC submission and must align perfectly with your architectural drawings.
